Abstract (en)
The rotor of the crusher receives the stones at its centre. It comprises three blades (20, 21) which, except on the ejecting edges (22), are protected against internal wear by their hollow shape which retains a protective layer of stones. These blades at the same time constitute the peripheral wall of the rotor and are formed gradually radially set back towards the rear from the ejecting edges in order to limit their external wear. <IMAGE>
Abstract (fr)
Le rotor du concasseur reçoit les pierres en son centre. Il comporte trois aubes (20, 21) qui, sauf sur les arêtes de projection (22) sont protégées contre l'usure interne par leur forme creuse qui retient une couche de pierres protectrice. Ces aubes constituent en même temps la paroi périphérique du rotor et sont formées avec un retrait radial progressif vers l'arrière à partir des arêtes de projection pour limiter leur usure externe.
